Im looking for an air tank to put in my truck box and hook up to my compressor. I want something around 10 gal that can hold at least 150 psi with its largest dimension no larger than 24". i have found some online but they want like $75 and thats for a 5 gal. i was hoping to spend more like $30. anyone have any ideas or places for me to check out? I have already been to the local hardware and auto stores with no luck.

I just want something to air up my tires and probably run an air horn in the near future. I know a smaller tank would work but my box is pretty big so why not use the space.

 

build one

you'd better be damn good at welding though

 

Yeah, it is amazing what air can leak through. We had quite a few leaks that we had to drill and re-weld when we built my bumper.

It is kinda pricey but works awesome! There's a few companies out there making them now.

Or you can get a CO2 tank for a keg like my buddy did haha

 

hey yeah...i got a few kegs layin around

theyre airtight

 

Get a scuba tank. Seriously. We use them for air ride.

 

my welding skills are nowhere near what they would need to be to make an air tight seal that would hold 150 psi.

neither the powertank or scuba tanks are any cheaper than like a viair 5 gal tank and my compressor would only be able to put it up to about 150 psi so volume is a good thing.

 

find a frat party and when everyone is drunk....steal the keg

 

yea, but does the viair compressor push enough air to run tools? no.

thats why i opted for the tank and not a compressor

 

My buddy bought 3 used scuba tanks at a swap meet for $75.

 

I'm gonna use some 8" pipe when I get ready to equip the truck with air. It's rated to 175 psi.

Know any sprinkler companies?

 

I ended up going to harbor freight and picked up a 10 gal rated for 200 psi for $35 and it has a 1 year warranty. now for the next step. anyone know of any decent air horns for under $100, maybe in the $50 range even? i have looked around and found some ranging from $5 to over $1000 but i dont really know what to look for. the decibel output must not mean much because they are all right around 130 or so and i didn't see any correlation between price and decibels.

 

You need a compressor too, the HF one is junk so don't go that route. Viair 380C's are really nice. Horns you can get some semi horns for pretty cheap

 

i already have a compressor. its one i have had for a while, probably junk but ill run it till it dies then replace it with a Viar 380 or somethin along those lines. where would i look for semi horns? how do i know if they are decent or not?

 

free off a train if you live near a yard

 

none nearby that i know of.

just out of curiosity, whats with all the tiny compressors that come with some of the horns like these

does that signify sh!tty horns?

 

^those are crappy, all they do is make a really really high pitched sound.



With 10 gallons of air you are going to want 2 Viair compressors. The rule is 1 compressor for every 5 gallons.


As for horns, your best bet is going to be buying a 4 piece black horn kit from hornblasters. I have it on my truck, it's the best non-nathan or lesie horn on the market.

 

that kit is about 3-4 times my price range. good to know about the tank size rule of thumb though.
